Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain a digital range sensor system by which the thickness of a transparent object can be measured, by a method wherein light from a source is focused in a small spot on a target, an optical element and a prism are fixed to the focus of light reflected from the target and the light is directed to the active face of a detector at an angle close to a vertical angle of incidence. SOLUTION: A digital range sensor 10 is divided into a transmitter 12 and a receiver 14. Light from a laser diode 16 is collimated by a collimating lens 22 so as to irradiate a target 18 via a focusing lens 14 and an output filter 26. Regarding light reflected by the target 18, the wavelength of light which is not desirable because of minimizing the sensitivity of the stray light of the sensor 10 is removed by a filter 32, and the light is optimized regarding a finite conjugate used for a map in an operating range by a detector 20 by using a triplet lens assembly 34. A beam of light radiated from the lens assembly 34 refers to light generated from a prism 42 via a front mirror 40 so as to be nearly vertically incident, the detector 20 is irradiated, and a reflection loss and a ghost at the detector 20 are reduced.

IPC: B66F11/04
Filed: 1988-03-23
Abstract: PURPOSE:To ensure safety in high-place works and enhance the working efficiency by selecting the safe revolution circle of a boom on the basis of signal from a left/right region selector switch to be changed over according to the overhang amount of an outrigger and the left/right position of the boom. CONSTITUTION:Signal about the left/right outrigger overhang positions by sensing means 13R, 13L and a judging means 16 are changed over by the signal from a boom left/right position sensing means 14. The signal is fed into a safe region judgement drive command means 20 via a left/right region selector switch 17, and a revolution circle selecting part 21 selects a safe revolution circle in the left or right region. On the basis of this safe revolution circle, a safe region judging part 23 actuates a boom elongation/fall restricting device 44 when the safe revolution circle is exceeded by the revolution circle or gondola, which is calculated from the amount of elongation and angle of rising/falling of the boom given by sensing means 11, 12. When a revolving direction sensing means 26 senses transition from the fore-and-aft region to the left/right region, a boom revolution regular direction restricting means 36 is actuated. Thus high-place works can be carried out safely and effectively.

Filed: 1984-04-09
Abstract: PURPOSE:To uniform the sound frequency characteristic in a sound field by superimposing an original signal and a signal changing the characteristic of the original signal mutually and using the result as a speaker signal. CONSTITUTION:The original signal input is delayed by a delay device 9 and impressed to a level adjusting device 10. The signal subject to level control is inputted to an inverter 11 and a buffer 12 and the output of the inverter 11 and the buffer 12 is selected and led out alternatively by a switch 13.

CONSTITUTION:The upper communicating pipe 6 and the lower communicating tank 7 are provided at each partition wall 5. The pipe 6 is located so that water surface comes to an upper end part thereof when the water tank is filled up with water (at normal time), while the pipe 67 is so disposed in the manner that the lower end thereof comes into contact with the bottom surface of the tank, and functions also as a drain pipe. Lukewarm water fed into a return tank 2 flows into the adjacent water tank 3 by passing through the pipe 6, and in addition, generates a water flow passing through the pipe 7. A vertical water flow is induced in the water tank due to the difference in water flow rate, a similar flow is generated also in the adjacent water tanks, and cold water is sequentially replaced by lukewarm water.

Abstract: PURPOSE: To prevent the generation of eddy on a surface layer at the time of water intake so as to perform smooth surface water intake by blocking a clearance between an upper surface and side walls on the right and left of a mouth section and arranging blocking materials which prevent water stream on a top face, a bottom face, and both sides on the right and left of the mouth section. CONSTITUTION: A wire rope is wound up and lowered by a drive mechanism to lift and lower a water intake pipe and a mouth section 3, and a water inlet 3a is arranged in the water on a surface layer to perform surface layer water intake. Next, hot water on the surface layer flows in from the front of the mouth section 3, and a part of hot water passes an upper section or sides on the right and left of the mouth section 3 and goes toward the rear surface side of the mouth section 3. However, each blocking material 5, 6 in the upper section and on sides prevents hot water from reaching the rear surface side of the mouth section 3.  Moreover, the blocking materials 5, 6 prevent hot water from flowing out in the forward direction of the mouth section 3 at the time of water intake, and a part on the rear surface side of the mouth section 3 becomes a pool to perform smooth surface water intake.

Filed: 1986-03-31
Abstract: PURPOSE:To eliminate the need for an instrument made of a special material and to measure an antigen or antibody in a short period by bringing the antigen, antibody and complement constituting component conjugated labeled matter into reaction in a suspended or dissolved state. CONSTITUTION:The antigen or antibody is measured by bringing the antigen, antibody and the complement constituting component conjugated the labeled matter into reaction in the suspended or dissolved state, then removing the unconjugated matter and quantitatively determining the conjugated labeled matter. Since the antigen, antibody and the complement constituting component conjugated with the labeled matter are brought into reaction in the suspended or dissolved state, the use of a vessel made of the special material having good adsorptivity for fixing the antigen, etc., is not always required. The conjugate formed after the reaction of the antigen, antibody and the labeled complement constituting component is separated. The excessive labeled complement constituting component failing to be brought into the reaction and the materials which act disturbingly in the subsequent process are removed by such operation.
